The preparation and properties of diethyl, di-n-propyl-, di-isopropyl-, of certain of the methyl and ethyl iodide adducts and the oxides, sulphides, and selenides are described. Diethyl and di-isopropylaminophenylphosphines have been shown to rearrange to the corresponding N-alkyldialkylaminophosphazenes, polycyclo(phenylphosphine), and alkylarnines. The infrared and n.m.r. spectra of some of J. Chem. SOC.

ALTHOUGH a few examples of aminophosphine ring atoms have been described.

The preparations and properties of certain bisdialkylaminophenylphosphines, Ph*P(NR,), and Ph-P(NR',) *NR,, and of diethylaminodiphenylphosphine, Ph,PNEt,, are described. 1 : 1 Compounds with methyl iodide are formed. The location of the methyl group in the adduct with Ph*P(NEt,), has been established by nuclear magnetic resonance studies. Complex formation with mercuric iodide is reported.COMPOUNDS in which tervalent phosphorus is directly bound to nitrogen have been little investigated so far, although they are clearly of interest both as potential ligands and as precursors of possible polymeric material. The first investigation of these aminophosphines, by Michaelis,l led to the preparation of compounds in the series Cl,P.
